A block of mass m 2 kg is placed on a rough horizontal surface and is being acted upon by a time dependant force F N 2t where t is in second The coefficient of static friction between the block and the horizontal surface is 0 20 The frictional force f developed between the block and the surface versus force F N plot is as shown 2 kg 1 2 5 m s 101 f N F N 2t 1 N N F N The velocity of the block at t 4s will be 2 5 m s www
